In clinical practice, the effectiveness of acne-scar-repair toner varies from person to person and must be evaluated based on individual circumstances. The recommended usage is as follows: 1. First, thoroughly cleanse the skin and gently pat dry the surface moisture. 2. Using a cotton swab, apply a small amount of the acne-scar-repair toner directly onto the acne-scar area—take care not to apply it over too large an area. 3. If the treated skin appears noticeably whitened after application, rinse the area thoroughly with water immediately.
